JOSEPH SHARPE, OF PATERSON, NEV JERSEY.

SPECIFICATION forming part of Letters Patent No. 607,488, dated July 19, 1898.

Application led October 2. 1897.

To @ZZ whom, it may concern:

Be it known that I, JOSEPH SHARPE, a citizen of the United States, residing in Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in vBrick-lVlachines; and I do hereby declare the following-to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my present invention is to provide a machine for making and pressing` bricks of simple, strong, anddurable construction, reliable and efficient inoperation, and in which machine the feed-box and the damper or valve of the supply-spout are operated automatically. A further Objectis to provide said machine with a mold-box, a movable mold-cap, and with dies, whereby the bricks manufactured are rough on their large or connecting surfaces and smooth on their ends and faces.

The invention consists in the improved brick-machine, in the feed-bOX-operating mechanism, in the straining-bars and the means for operating the same, in the mechanism for automatically operating the damper or valve of the supply-spout, and in the combi-nation and arrangements of the various parts, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claims. l

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure l is a side elevation ,of my improved brick-making machine, the movable feed-spout being broken away; Fig. 2, a sectional view on the line a: :c of Fig. l; Fig. 3, an elevation of the opposite side of themachine as illustrated in Fig. 1; Fig. 4, a detail view of a portion of a certain spur-wheel and Q of its externally toothed or corrugated hub; Fig. 5, a sectional View of one of a series of cam-disks adapted to be adjustably arranged on the said toothed or corrugated hub of the spur-wheel; Fig. G, a detail elevation of the upper portion of Fig. 3, the near frame and certain operating parts being removed, the

serial 110.653,78. on' man inain driving-shaft l), on which is mountedand on each side of the machine a pinion c, meshing into spur-wheel d, secured on the parallel crank-shaft c. The crank f of said crank-shaft c is connected by a pitman g with one end of the lever c', theV other end of which is fulcrumed on the rod c, suitably supported vin the frame CL and parallel with and below the main driving-shaft b.

On the connecting-pin c? is pivotally arranged one end of link h, while the other end `of said link is connected by a pin 3 with the vupper forked portion of an arm k, the lower end of which terminates in an elongated hub m', having its bearings in vertical elliptical slots m2 in the frame a. On the pin 3 is also pivotally secured one end of arm m, the other end of which is pivotally connected with the lower portion of the follower or reciprocating head m3, suitably guided in the frame a, as illustrated in Fig. 2.

On each spur-wheel d are arranged two horizontally-projecting pins or studs d d2, adapted to engage and operate the longer arm of a lever o, fulcrumed, as at o', adjacent to the hub m' andhaving its shorter curved arm o2 engaging the said hub, as clearly illustrated in Figs. 1, 2, and 3 of the drawings.

On the hub m and at or near each end thereof is mounted a double straining-bar p, to the screw-threaded upper portions of which is adj ustably secured the mold-cap p', adapted to engage and bear during certain stages of operation upon the top of the mold-boxp2, which latter is suitably supported on the frame aand above the follower or reciprocating head m3.

lVthin the mold-box is arranged the reciprocating block p3, carrying at its upper end the dies in the usual and well-known manner. On each side of the block is pivotally arranged, as at p4, the upper portion of a link p5, the lower portion of which is jointed with one arm of lever p6, fulcrumed, as at p7, to the frame a and having its free end in the IOO path of and adapted to be operated bya cani T, arranged on a disk T', which latter is adjustably secured on the hub T2 of the spurwheel CZ. Said hub is for that purpose provided with a series of elongated teeth or corrugations, while the internal bore of the disk T is provided with a series of notches or corrugations snugly fitting upon the said series of teeth or corrugations on said hub.

The straining-bars p are limited in their forward motion by stops a and in their rearward motion by stops a2, projecting from and preferably integral with the frame a. A spiral spring d3 is secured with one end to the upper portion of its respective straining-bar, while its other end is secured to the said frame a, as clearly illustrated in Figs. l an d 2.

rlhose portions of the straining-bars which are adapted to engage the stops a and a2 are provided with suitable elastic cushions d10 and au. To about the central portion of one of said strainiug-bars-that is to say, to the straining-bar on one side of the machine-is pivotally secured, as at p", a bar or arm p9, having its rearward end slidingly arranged in a guide bracket or bridge p11 and adapted to be engaged by a cam T3, arranged on a disk T", which latter is of similar construction to the disk T' and is also mounted on the hub T2 of the spur-wheel CZ. On said hub T2 and adjacent to the disk T1 is mounted a disk T6, provided with a cam T5, adapted to engage and operate the depending rod T1, pivotally connected with the shorter arm TS of an an gle-lever fulcruined, as at T11, to an auxiliary bracket a and havin its longer arm T10 bent upward and pivotally connected through a link T11 with the feed-box s, which latter is slidingly arranged on the table s and is provided in its bottom with an opening adapted to be brought in alinement with the mold-box 192.

The feed-box s is of ordinary construction and is provided with a partition s2, extending from the rear upper portion of said box to about the opening in the bottom thereof. On each side of the box are secured downwardly-extending brackets s3 s3, having their lower portions slidingly arranged on rods 31 s1,whereby additional steadiness is furnished to the feed-box while being moved or operated. To the rear upper portion and on one side of said feed-box .s is pivotally secured a link q, the free end of which is jointed to the longer arm of a lever q', fulcruined, as at q2, on the auxiliary bracket a and having its shorter arm in the path of and adapted to be operated by a cam T12, projecting .from a disk T13, which latter is mounted on the hub T2 of the spur-wheel and adjacent to the disk T. A disk T1, with cam T15, is also arranged on said hub and alongside of the disk T13 and is adapted to operate the shorter arm of the lever t', fulcrumed as at Q2 and having the free end of its longer arm connected by a brace or rod v' with the strainin g-bar 13,(011 one side of the machine.)

The reciprocating block p3, carrying the dies, is limited in its downward movement by stops adj ustably arranged in brackets projecting from the side of the 'frame a.

On a platform or [ioor y1 above the machine is mounted the fixed feed spout 11/2, to the lower portion of which is hinged, as at gij', the movable spout-section y, extending with its lower end into the feed-box s.

The fixed feed-spout y2 is provided with a valve or damper y1, to the outwardly-projecting arm of which is jointed, as at '.1/5, one end of lever y1", fulcrumed, as at 7/7, to a bracket ys, and having its free arm loosely and slidingly arranged in a bridge or bracket y1', mounted on the inside of the feed-box s, all as clearly illustrated in Figs. 3, (i, and 7 of the drawings.

On the moldcap p is arranged a nose or projection p15, adapted to engage the front portion of the feed-box s to thus start the lat ter in its rearward movement, which projection may be used either alone for that purpose or in connection with the link q, fulerumed lever l, and cam T12 of disk T13, or, if desired, can be dispensed with, in which case the last-mentioned link-and-lever connection.. will perform the desired operation.

In operation the spur-wheel d is rotated in the direction of the arrow R, Figs. l and 3. The cam T5 operates the depending rod or lever T7 and thus the fulcruined angle-lever TS T10, whereby the feed-box .s is moved from left to right, Fig. l-that is to say, the opening in its bottoni is brought in alineinent with and over the dies in the m old-box p2. Simultaneously the fulcrumed lever 1/11 is being operated-that is to say, its lower end comes in Contact with the rear portion of the bridge or bracket yg, whereby the upper portion of said lever is moved from left to right, Fig. 3, thus opening the valve or damper y1 and allowing a certain amount of molding material to enterfrom the fixed feed-spout and through the movable spout into the feed-box 3 and from there into the mold-bovpL and upon the top of l[he dies. The shaft e in its further rotation causes the cams T12 and T15 to engage the shorter arms of the levers q' and fu, respectively, while simultaneously the projecting pins cl2 of the spur-wheels d depress the longer arms of the f ulcrumed levers o, thereby raising the hub in and straining-bars p and thus the mold-cap p' over the corner or edge of the mold-box p2. The straining-bars are now moved backward, Fig. 3, by means of the connecting brace or. rod n and fulcrumed lever n, while simultaneously the feed-box .5- is returned to its original position, the damper y* being closed. The mold cap p is thus brought upon the mold-box p2, and siinultaneously the toggle-levers exert pressure upon the follower or reciprocating head m3 and thus move the latter upward, which in turn operates the reciprocatii'lg block p3 and the dies carried thereby, thus forming the bricks, as will be manifest. About that time the pins d of the spur-wheels d have again depressed IOO IIO

IZO

the levers o and thus raised the mold-cap p suficient to allow it to return to its normal position, which return movement is started by the cam r3 of disk r4 engaging the free end of sliding bar or arm p9, and thus swinging the straining-bars p backward, Fig. l, which' latter thereafter return gradually against the action of the spiral springs as to their normal position by gravity. Simultaneously the cam r operates the fulcrumed lever p6, which in turn raises the links p5 and thus forces the reciprocating block upward until the d'ies are above the plane of the moldboX, when the finished bricks can be conveniently removed. The heretofore-described operation is then repeated. Y

The advantages of the double straining-bars are obvious: An equal strain is exerted over both molds and so prevents either of the bricks from having a feather-edge or of being of unequal thickness, while the spiral spring a3 and elastic cushions in conjunction with the stops c and a2 reduce the jar of said straining-bars when falling back to their normal position by gravity or their own Weight.
